CI854 version of the running primary not preferred
Got a question. I found a similar question in the DB but not exact what I was after.
In the Unit status of the CI854, the Extendedstatus end the LatchedExtendedStatus the warning "Not Preferred version primary". How the solve this? I have the same and as im trying to upgrade firmware, it gives the message already inapplication. Does it mean I need to upgrade the HW library in order to get rid of this alarm? ( Profibus 2.1.7 HWlib)
Probably too old revision for your system version to meet requirement/functional level.
Compare the HW revision (PR:A,B,C...) seen in controller log vs the Control IT release notes for the version you are running.
It may seem to work just fine, but for full support & functionality the hardware revision mentioned as Minimum Supported in release notes must be met.
